Re: [WiX-users] Read file content from CA

[Niklas Söderberg]

Hi,
Yeah, I considered that option as well. Felt like duplication though (it is
actually 8-10 files I might need to read, albeit small ones), and I wasn't
entirely comfortable with that. Perhaps I will choose that solution after
all, now that I've explored the alternative.

Thanks for you opinion!

Niklas
